Decolonized biodiversity crisis: How colonial-era specimen collections and unsustainable hunting reveal systemic decline of Madagascar’s flying foxes, with implications for island ecosystems and global conservation ethics

The current crisis is a direct consequence of colonial-era specimen collection, which began in the 19th century when European explorers and missionaries systematically hunted and preserved Madagascar’s wildlife for Western museums. These collections were not neutral acts of science but part of a broader project of extracting knowledge and resources from colonized territories, often through violent means. Additionally, the introduction of invasive species (e.g., rats, cats) by European settlers further destabilized flying fox populations, creating a compounded ecological crisis. The decline of these bats also mirrors historical patterns of island biodiversity collapse, such as the extinction of Madagascar’s giant lemurs and the near-extinction of Hawaii’s native birds due to similar colonial disruptions. Understanding this history is critical to addressing the root causes of the current decline, as it reveals how present-day conservation efforts remain entangled in the legacies of colonialism.
The decline of Madagascar’s flying foxes is not an isolated ecological event but a symptom of a deeply interconnected crisis rooted in colonialism, globalization, and the erasure of Indigenous knowledge.
The very museum specimens used to document this decline were often extracted through violent colonial practices, which disrupted the ecological and cultural systems that once sustained these bats. Meanwhile, contemporary commercial hunting reflects the persistence of neocolonial trade networks, where global demand for bushmeat and traditional medicines drives localized exploitation. The absence of Malagasy voices in mainstream narratives obscures the fact that many communities view flying foxes as sacred beings tied to ancestral spirits and ecological balance, not merely as resources to be exploited. Historical parallels—such as the collapse of island biodiversity under colonialism—reveal that this crisis is not unique but part of a broader pattern of ecological and cultural destruction. To address it, solutions must center Indigenous-led conservation, reform global trade practices, restore sacred landscapes, and revive cultural narratives that once protected these keystone species. Without confronting these systemic roots, conservation efforts will remain reactive and insufficient, leaving Madagascar’s flying foxes—and its ecosystems—at further risk.
